Water/Wastewater Treatment Water Treatment for the Dye Industry
Textile dyeing industry is one of the most water consuming industries after thermal, engineering pulp and paper industries. In India water consumed by textile industries in the year of 2010 was around 1900 Mm3 (Million cubic meters) and effluent water generated was around 75 per cent of its intake.

As the textile industry is one of the most water consuming industries in the country, water treatment systems play an important role here. Biological oxidation process is widely used and recommended due to its positive results, lower sludge generation and low running costs. The main objective of the biological treatment is the oxidation of the dissolved and particulate biodegradable constituents so that the polluting organic and inorganic compounds are removed or significantly reduced.
How to Neutralize Acids in the Wastewater Stream
Dye effluent has higher pH that needs to be neutralised for bacterial activity. The removal of excess acidity or alkalinity by a chemical agent is called neutralisation. Industrial waters exposed to extremely high or low pH values require a neutralisation process before they can be sent to biological treatment or environment.
